This is probably one of the toughest parts of the DLC. Keeping your allies alive might be tough if you dont use renew ammunition when available and stay with your allies to protect them. Spam your smoke bombs!! This will help you eliminate targets fast and keep health bars of allies higher before the final parts! Feel free to use my strategies. And please NO NEGATIVE OR STUPID, IRRELEVANT COMMENTS!
If you dont like my gameplay simply dont watch and dont comment!
1-What's a DLC? == A DLC stands for "downloadable content" meaning its something you can download from PSN for a video game.
2. Do I have to play the game all over again to play this sequence 12? == NO, If you already finished the game, after DLC installation you will be automatically taken to sequence 12. But if you havent finished sequence 11 I dont know what happens, you probably cant until you get to the certain sequence.
3. My allies constantly die on "Hold the Fort", what do I do? == READ THE DESCRIPTION FOR A STRATEGY! ^_^
